The value of pythonLocation is inconsistent between CPython and PyPy

On both pypy2 and pypy3 the bin path segment is included in the pythonLocation variable:

pypy3 pythonLocation

/opt/hostedtoolcache/PyPy/3.6.9/x64/bin

pypy2 pythonLocation

/opt/hostedtoolcache/PyPy/2.7.13/x64/bin

But for the CPython versions it isn't.
3.6 pythonLocation

/opt/hostedtoolcache/Python/3.6.10/x64

2.7 pythonLocation

/opt/hostedtoolcache/Python/2.7.17/x64

I would expect the PyPy versions to be consistent with CPython builds
